Objective:To evaluate the value of autologous platelet-rich plasma (aPRP) separation-retransfusion for blood conservation in the patients undergoing thoracolumbar laminectomy.Methods:Sixty American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients, aged 18-60 yr, with body mass index of 19-30 kg/m 2, scheduled for elective thoracolumbar laminectomy, were divided into 2 groups ( n=30 each) using a random number table method: conventional blood conservation group (group C) and aPRP blood conservation group (group aPRP). Group C received tranexamic acid and autologous blood salvage-retransfusion. Group aPRP received aPRP separation-retransfusion, tranexamic acid and autologous blood salvage-retransfusion. The volume of allogeneic blood transfused, percentage of patients who did not need the allogeneic blood transfusion and adverse reactions were recorded. Venous blood samples were collected for blood routine examination and for determination of the plasma concentrations of interleukin-6 (IL-6) and IL-10 at 1 day before operation (T 0), when the volume of blood loss reached 500 ml (T 1), immediately after surgery (T 2), and at 24 and 48 h after surgery (T 3, 4). The incidence of hypoxemia and amount of 24-h wound drainage were recorded. Results:Compared with group C, the amount of allogeneic red blood cells, plasma transfused and 24-h wound drainage were significantly decreased ( P<0.05), the percentage of patients who did not need the allogeneic red blood cell and plasma transfusion was increased (30% vs 47%, 10% vs 60%, P<0.05), the plasma concentrations of IL-6 and IL-10 at T 2-4 were significantly decreased ( P<0.05), and the incidence of hypoxemia in PACU was decreased in group aPRP (27% vs 10%, P<0.05). Conclusions:aPRP separation-retransfusion can provide marked improvement in conventional blood conservation in the patients undergoing thoracolumbar laminectomy.

OBJECTIVE To analyze the current status， hotspots and development trends of research on the treatment of non-alcoholic fatty liver disease （NAFLD）， providing reference for subsequent research. METHODS Searching the Web of Science database， the literature related to the treatment of NAFLD from the establishment of the database to December 31， 2022 were collected. CiteSpace 6.1.R6 was used to construct a visual atlas， perform collaborative network analysis on authors， countries and institutions， and conduct keyword co-occurrence， clustering and emergence analysis to explore its research status and hotspots. RESULTS A total of 3 882 articles were included， and the number of publications had been increasing year by year. The top three countries in terms of publication volume were China， the United States， and Japan. The author with the highest volume of publications was Sanyal from the United States （37 articles）， while the institution with the highest volume of publications was the University of California， San Diego （75 articles）. A closely connected research team abroad mainly conducted large-scale randomized controlled trials （RCT） to evaluate the effectiveness and safety of various interventions， including medication and lifestyle， in treating NAFLD. However， domestic researches mainly focused on basic researches about the treatment of NAFLD with effective medicinal ingredients， and were characterized by traditional Chinese medicine. There were relatively few high-quality large-scale RCT studies related to it. Keyword analysis showed that researches in various countries mainly focused on regulating liver oxidative stress and inflammation， improving the overall balance of glucose and lipid metabolism. Except for hypoglycemic drugs， drugs that act on various comprehensive metabolic homeostasis targets in the body had entered clinical research， and had enormous therapeutic potential. CONCLUSIONS The research on NAFLD treatment continues to grow in popularity and tends to research targets and drugs for regulating systemic metabolic homeostasis. As the main force of research， China should strengthen communication with the international community， grasp the trends and directions of basic research， attach importance to clinical research， and continuously tap the therapeutic potential of traditional Chinese medicine.

Plant adaptation to adverse environment depends on transmitting the external stress signals into internal signaling pathways, and thus forming a variety of stress response mechanisms during evolution. Brassinosteroids (BRs) is a steroid hormone and widely involved in plant growth, development and stress response. BR is perceived by cell surface receptors, including the receptor brassinosteroid-insensitive 1 (BRI1) and the co-receptor BRI1-associated-kinase 1 (BAK1), which in turn trigger a signaling cascade that leads to the inhibition of BIN2 and activation of BES1/BZR1 transcription factors. BES1/BZR1 can directly regulate the expression of thousands of downstream responsive genes. Studies in the model plant Arabidopsis thaliana have shown that members of BR biosynthesis and signal transduction pathways, particularly protein kinase BIN2 and its downstream transcription factors BES1/BZR1, can be extensively regulated by a variety of environmental factors. In this paper, we summarize recent progresses on how BR biosynthesis and signal transduction are regulated by complex environmental factors, as well as how BR and environmental factors co-regulate crop agronomic traits, cold and salt stress responses.

Objective:To investigate the relationship between common functional gastrointestinal diseases symptoms with psychological factors, diet and lifestyles by using the network analysis method which has achieved great success in the field of psychology in recent years.Method:A questionnaire survey was conducted in two military units using the cluster sampling method during July 2020, and a total of 1 805 subjects were included. Functional gastrointestinal disease symptoms were evaluated with the Gastrointestinal Symptom Rating Scale (GSRS). The state, trait anxiety scale and stress response scale were used to evaluate the mental and psychological state by self-evaluation. R was used to build the network and calculate statistical parameters.Results:1 486 of the 1 805 subjects (82.3%) had experienced functional gastrointestinal diseases symptoms within 2 weeks, but most of them were mild. Network analysis shows that there was a strong interaction between digestive system symptoms with different clinical manifestations (Spearman coefficient ranges 0.31-0.56). There was a clear relationship between functional gastrointestinal symptoms and mental and psychological factors (Spearman coefficient ranges 0.16-0.27), but there was no clear interaction with diet, age, education level, body mass index, etc. Functional gastrointestinal diseases symptoms were connected with mental and psychological factors through two nodes: stress and indigestion. The stability coefficient of node strength correlation was 0.75, indicating that the network was stable.Conclusions:The current study revealed the network structure and features of functional gastrointestinal diseases symptoms with mental and psychological factors. The key linking nodes provided potential interfering target for controlling functional gastrointestinal symptoms related to mental and psychological factors.

Objective:To evaluate the optimization strategy of anesthesia for liver cancer resection using serratus anterior plane block-posterior rectus sheath block-general anesthesia.Methods:One hundred patients, aged 30-64 yr, with body mass index of 18-30 kg/m 2, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, with liver function Child-Pugh grade A or B, scheduled for elective liver cancer resection under general anesthesia, were divided into serratus anterior plane block combined with posterior rectus sheath block group (group S, n=50) and thoracic paravertebral block group (group T, n=50) using a random number table method.Ultrasound-guided serratus anterior plane block (20 ml) combined with posterior rectus sheath block (10 ml) was performed using 0.375% ropivacaine in group S. Ultrasound-guided paravertebral block was performed at T 7 and T 9(15 ml for each site) with 0.375% ropivacaine in group T. Anesthesia was induced with intravenous midazolam, propofol, sufentanil and cisatracurium and maintained with intravenous infusion of propofol and remifentanil and intermittent intravenous boluses of cisatracurium.BIS value was maintained at 40-60 during operation.Patient-controlled intravenous analgesia (PCIA) was performed with sufentanil and flurbiprofen at the end of operation, and oxycodone 5 mg was intravenously injected as rescue analgesic when the VAS score>3.The onset time and operation time of nerve block were recorded.The intraoperative consumption of sufentanil and remifentanil and occurrence of cardiovascular events within 30 min after skin incision were recorded.The effective pressing times of PCA and requirement for rescue analgesia within 48 h after operation were recorded.The recovery quality was measured using the 40-item quality of recovery questionnaire at 24 h before surgery and 24 and 48 h after surgery.Peripheral venous blood samples were collected at 24 h before surgery and 24 h and 7 days after surgery to determine the concentrations of interleukin-17 and interferon-gamma in serum.The postoperative time to first flatus, first ambulation time, and length of hospital stay were recorded.The nausea and vomiting, respiratory depression, skin itching, puncture site infection, pneumothorax and other adverse reactions were recorded within 48 h after operation. Results:Compared with group T, the operation time of nerve block was significantly shortened, the incidence of intraoperative hypotension was decreased ( P<0.05), and no significant change was found in the onset time of nerve block, intraoperative consumption of sufentanil and remifentanil, postoperative requirement for rescue analgesia, effective pressing times of PCA, time to first flatus, first ambulation time, and length of hospital stay, and 40-item quality of recovery scores and serum concentrations of interleukin-17 and interferon-gamma at each time point in group S ( P>0.05). No postoperative adverse reactions were found in either group. Conclusions:Compared with thoracic paravertebral nerve block combined with general anesthesia, serratus anterior plane block-posterior rectus sheath block-general anesthesia has shorter operation time and lower incidence of intraoperative hypotension when used for liver cancer resection.

Objective:To determine the median effective dose (ED 50) of esketamine for preoperative sedation in different aged pediatric patients. Methods:Pediatric patients, aged 1-6 yr, of American Society of Anaesthesiologists physical status Ⅰ, with the preoperative parental Separation Anxiety Scale (PSAS) score ≥3, undergoing elective surgery under general anesthesia, were selected.According to the age, the children were divided into 1 yr≤age<4 yr low-age group (group L) and 4 yr≤age< 6 yr high-age group (group H). Esketamine 0.5 mg/kg was intravenously injected in the first child in each group.The dose in the next child was determined according to PSAS scores, and the two consecutive dose gradient was 0.1 mg/kg; when the PSAS score in the previous child was ≥3, the dose in the next child was increased; when the PSAS score in the previous child was< 3, the dose in the next child was decreased until appearance of 7 turning points, and then the experiment was terminated.The ED 50 and 95% confidence interval of esketamine for preoperative sedation were calculated by probit analysis. Results:A total of 54 children were enrolled in this study, including 26 cases in group L and 28 cases in group H. The ED 50 and 95% confidence interval of esketamine were 0.413 (0.314-0.530) mg/kg and 0.282 (0.252-0.318) mg/kg in group L and group H, respectively.Compared with group L, ED 50 of esketamine was significantly decreased in group H ( P<0.05). Conclusions:The ED 50 of esketamine for preoperative sedation is 0.413 mg/kg in pediatric patients of 1 yr≤age<4 yr old and 0.282 mg/kg in those of 4 yr≤age<6 yr old, and the efficacy of esketamine for preoperative sedation increases with age.

Objective:To summarize the clinical experience of changing the membranous pulmonary system during extracorporeal membrane oxygenation(ECMO) in infants after congenital heart disease opration with cardiopulmonary bypass.Methods:From January to September in 2019, 6 cases of congenital heart disease with cardio-pulmonary bypass in our hospital were analyzed retrospectively, whose membrane obstruction occurred during ECMO treatment and replaced successfully.The hemodynamics and blood gas before and after replacement of ECMO system were observed, and the experience was summarized.Results:Six patients(3 males and 3 females), aging from 1 to 3 months and weighing from 3.0 to 4.9 kg, were received VA-ECMO adjuvant therapy.The ECMO system replacement process was smooth and took 175-209 s. The hemodynamic of the children was stable.The ECMO support time was 134-249 h. After the improvement of cardiac systolic function, all children were successfully withdrawn and survived.Conclusion:The improved method of liquid replacement in ECMO system can make full use of the blood components in the original system and avoid the loss of blood tangible components.According to the plan of rapid replacement, the risk of replacement will not be increased.

Objective:To compare the curative effects of different venous cannulas and drainage to improve patient's whole body oxygenation during the auxiliary process of venous-arterial extracorporeal membrane oxygenation (VA-ECMO) in lung transplantation.Methods:From December 2016 to December 2019, 12 patients who were assisted by VA-ECMO in one lung transplantation in People's Hospital of Henan Province were selected as the research objects. According to the number of side holes of venous cannulas, they were divided into two groups: one group with few side holes and other group with multiple side holes. The differences in blood gas indexes among the right radial artery, left radial artery, and right internal jugular vein before and after assistance were compared, and the assistance effect was evaluated.Results:The arterial partial pressure of oxygen (PaO 2) of blood gas indexes of the right and left radial arteries in both groups were significantly higher than that before assistance [mmHg (1 mmHg = 0.133 kPa): right and left radial artery in few side holes group: 79.5±4.2 vs. 48.3±3.8 and 88.1±3.5 vs. 48.3±3.8; right and left radial artery in multiple side holes group: 67.7±5.9 vs. 48.7±3.2 and 84.0±3.8 vs. 48.7±3.2, all P < 0.05]. The arterial partial pressure of carbon dioxide (PaCO 2) of blood gas index was significantly lower than that before assistance (mmHg: 44.2±2.6 vs. 71.7±4.4 for the right radial artery and 44.7±1.4 vs. 71.7±4.4 for the left radial artery in the group with few side holes; 46.2±2.1 vs. 71.2±3.5 for the right radial artery and 44.1±1.9 vs. 71.2±3.5 for the left radial artery in the group with multiple side holes, all P < 0.05). The partial pressure of oxygen in venous blood (PvO 2) of blood gas index of ECMO system in the group with few side holes was significantly lower than that of the multiport side holes group (mmHg: 56.4±3.2 vs. 88.7±1.5, P < 0.01), and the partial pressure of carbon dioxide in venous blood (PvCO 2) was significantly higher than that of multiport side holes group (mmHg: 63.6±3.7 vs. 44.2±1.7, P < 0.01). Conclusions:When VA-ECMO is used in lung transplantation, the superior vena cava blood flow can be fully drained by using intravenous cannula with few side holes. It can effectively improve the oxygenation of the upper body of lung transplant patients, avoid the dilemma of hypoxemia in the upper body and hyperxemia in the lower body, provide more effective assistance to patients undergoing single lung transplantation, and is more meaningful for improving the oxygenation status of the whole body in patients undergoing single lung transplantation.
